Q4. A simple linear regression model is fit to data and the resulting model is y-hat = 4.3x-15. What is the
value of the slope and what is its interpretation?
The slope is -15 and means that when x increases by 1, y will decrease by 15
The slope is 4.3 and means that whenever x is increased, y will increase by 4.3
The slope is -15 and means that whenever x is increased, y will decrease by 15
The slope is 4.3 and means that whenever x increases by 1, y will increase by 4.3
